My wife bought her ‘15 F3-S used 3 years ago w/ ~7K miles on it. Now has ~13K miles. I have not changed the HCM filter myself, unknown whether it was done previously. Am gonna change engine oil/filter soon, but was wondering if there is a problem with leaving the original HCM filter in for 10+ years. Saw the cut-away of that filter posted up by a member here - not much to it. Hate to spend the $ on something that’s not needed. What say ye?
